A flint knapper’s site. Flakes everywhere, all from the same crystalline quartzite core. The knapper had built himself a seat by propping a sandstone slab against two smaller rocks. Bill said he must have been an old guy with arthritis who had to get his chair just right.
To me the site seemed recent, say 300-500 years old: the slab had not toppled, the flakes had traveled only about thirty feet down the slope. But the quartzite was typically Archaic, which would put it back a thousand years at least. Possibly much more.
